Musa plant named &#39;0714&#39;

ABSTRACT

A new cultivar of  Musa  named ‘0714’ grown for its ornamental qualities, and whose leaf color is saturated burgundy-brown with uniformly distributed very small elongated green blotches. In combination these traits set ‘0714’ apart from all other existing varieties of  Musa  known to the inventor.

DENOMINATION ‘0714’ BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Musa sumatrana, hereinafter referred to by the cultivar name, ‘0714’.

Musa sumatrana, whose common name is The Blood Banana or Red Banana Tree, is a native plant of Sumatra, Indonesia. Musa sumatrana can also be found described in the literature as Musa acuminata subsp. sumatrana or Musa acuminata subsp. zebrina. References to “sumatrana” as a cultivar name thus: ‘Sumatrana’, are erroneous: the plant is a native species or subspecies.

Musa sumatrana is noted for its elegant form consisting of broad glaucous green leaves with varying degrees of irregular “blotching” of burgundy-brown coloration. Juvenile plants of Musa sumatrana exhibit very little blotching, whereas mature plants may exhibit leaf blotching on half to two-thirds of the leaf surface area.

In August 2006, the inventor received a single plant of the species Musa sumatrana (unpatented). The inventor observed that this plant was distinct in that many of its leaves were unusually saturated with the burgundy-brown coloration, albeit with some green blotching. Although all of the leaves retained some small varying degrees of green, the whole plant appeared overall as burgundy-brown, rather than the reverse as is typical of the species.

The inventor, who is an experienced propagator of Musa by tissue culture, decided that the plant, though very attractive, was likely to be unstable in propagation and might revert over time to the green characteristic of its species. The inventor hoped that it would be possible to produce and isolate a new, distinct and stable clone by repeated cycles of tissue culture during which process all off-types would be discarded. Commencing in August 2006, at his laboratory in Tirat Yehuda, Israel, the inventor excised from the originally received plant the shoot tip of its pseudostem, containing the shoot meristem, and proceeded to establish new growth in vitro. Plants of Musa grow and proliferate (sucker) very rapidly under laboratory conditions and the inventor was able to carry out further propagations at approximately 4 week intervals. The resulting plants from each cycle were allowed to harden by growing at cooler temperature in order to increase the visibility of the burgundy-brown coloration and thereby to discard all plants which tended to grow as the species with predominantly green foliage. By February 2007, the inventor had completed four cycles of tissue culture with careful selection for the desired uniformity at each stage. After the fourth cycle, the inventor observed that all of the resulting plants were identical, with saturated burgundy-brown colored foliage which, upon close examination, exhibits uniformly distributed small green elongated blotches. This form, named ‘0714’ represents a new and distinct and stable variety of Musa sumatrana unlike any other varieties of Musa known to the inventor. The inventor has carried out further cycles of asexual reproduction, by tissue culture, both at his laboratory in Israel and under the inventor's supervision at a tissue culture laboratory in Bangkok, Thailand. The inventor has determined ‘0714’ is a new and stable variety of Musa which reproduces true to type in all its successive generations.

‘0714’ is derived from an unstable sport of the species Musa sumatrana, which is the parent variety and is the variety or species of Musa which most closely resembles ‘0714’. In comparison with Musa sumatrana’, ‘0714’ exhibits a burgundy-brown foliage color throughout, whereas Musa sumatrana’ is predominantly green with blotches of burgundy-brown.

This application claims the benefit of priority under 35 U.S.C. 119(f) of an application for European Community Plant Breeders Rights, Application No. 2007/0836, filed on Apr. 10, 2007.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and represent the distinguishing characteristics of the new Musa variety known as ‘0714’. These traits in combination distinguish ‘0714’ from all other existing varieties of Musa known to the inventor. ‘0714’ has not been tested under all possible conditions and phenotypic differences may be observed with variations in environmental, climatic, and cultural conditions, however, without any variance in genotype.

-   -   1. ‘0714’ is approximately 60 cm in height and 30 cm in width at         six months of age from propagation.     -   2. The juvenile, unhardened, foliage of ‘0714’ is pale         burgundy-brown is color, with pale green veins and pale green         leaf edge surfaces. As growth proceeds and the plant hardens,         these green regions become burgundy-brown in color.     -   3. The leaf color of a mature plant of ‘0714 is saturated         burgundy-brown with occasional uniformly distributed very small         elongated green blotches.

DESCRIPTION OF THE DRAWINGS

The accompanying color drawings illustrate the overall appearance of the new Musa variety ‘0714’, showing the color as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the drawing may differ from the color values cited in the detailed botanical description, which accurately describe the actual colors of the new variety ‘0714’.

The drawing labeled as FIG. 1 illustrates a typical plant of Musa sumatrana and shows the predominant green coloration of the foliage together with the characteristic irregular burgundy-brown blotches.

The drawing labeled as FIG.2 illustrates a plant in process of being stabilized by the inventor. The illustrated plant had been produced from the original discovered plant but was not considered sufficiently stable to be introduced.

The drawing labeled as FIG.3 illustrates greenhouse-grown juvenile plants of ‘0714’ which resulted from the first cycle of propagation after the inventor determined that he had successfully stabilized the variety.

The drawing labeled as FIG.4 provides a close-up view of a typical section of a fully expanded leaf on a mature plant of ‘0714’. The leaf color is saturated burgundy-brown with occasional uniformly distributed very small elongated green blotches.

The drawing labeled as FIG. 5 illustrates a side view of a six months old plant of ‘0714’ growing out of doors in Bangkok, Thailand.

The drawing labeled as FIG. 6 illustrates a top view of the same plant illustrated in FIG. 5.
